Abstract: A replaceable blade knife (1) comprises two elongate handle portions (3, 4) and a blade carrier (5) assembled together; the blade (6) protruding, or being arranged to protrude, from a front end (8) of the handle (2), between respective front ends (9, 10) of the two handle portions (3, 4). The upper handle portion (3) has a thumb-nail-sized aperture (26) through a rear end part thereof. When the knife (1) is assembled, the two handle portions (3, 4) are slid relatively longitudinally of one another, the upper handle portion (3) moving forwardly of the lower handle portion (4), until a latch part (31) near the rear end of the lower handle portion (4) clicks into latching engagement with the front edge (36) of the aperture (26) in the upper handle portion (3). The upper handle portion (3) is formed near its front end (9) with two downwardly projecting flank portions (14, 15), each said flank portion having an integral, forewardly projecting piece (16, 17) at the bottom of the flank portion. The front (10) of the lower handle portion (4) is formed with upwardly projecting flank portions (20, 21), each said flank portion having an integral, rearwardly projecting piece (22, 23) at the top of the flank portion, to overlie and hence interlock with a forwardly projecting piece (16, 17) at the bottom of the corresponding flank portion (14, 15) of the upper handle portion (3). At the rear edge of the aperture (26), the upper handle portion (3) is formed, at the bottom thereof, with a forwardly directed projection (27) which engages in a recess (28) at a rear wall (29) of the lower handle portion (4) to interlock the two handle portions (3, 4) together at the rear end of the handle (2).

Abstract: The present invention concerns a grid amplifier tube producing with an approximately constant gain at least a combination of a first signal for a short duration and a second signal for a longer duration. The maximum voltage of the first signal is higher than the maximum voltage of the second signal. To improve the efficiency of the tube, the anode polarization voltage is adjusted to a level enabling the tube to operate as a class B, AB or C amplifier and to produce the maximum voltage of the second signal but not the maximum voltage of the first signal. The class of the amplifier is made to vary towards class A for the duration of the first signal so that it produces the maximum voltage of the first signal. For this purpose at least one of the polarization voltages of the electrodes of the tube is made to vary. The present invention finds particular application to television transmitters operating in negative transmission systems.

Abstract: A biosensing system is described which determines whether a measured current is varying in accordance with a predetermined Cottrell current relationship. The system includes a test cell with at least a pair of electrodes which extend into a reaction zone, which reaction zone includes analyte reactants. An analog signal detector, in combination with a microprocessor, take plurality of current measurements between the electrodes over a plurality of succeeding measurement times, after a sample is placed in contact with the analyte reactants in the reaction zone. The microprocessor also stores a plurality of succeeding cpmparison constants which are derived by taking the inverse ratio of the square root of a measurement time divided by the square root of a subsequent measurement time. The microprocessor selects a pair of succeeding measurement times; derives a ratio of the currents measured at those times; and then compares the ratio of those currents with the comparison constant previously derived for the pair of succeeding measurement times. If the comparison indicates that the measured current ratio is dissimilar from the comparison constant, an indication is developed that the current between the electrodes is not varying in accordance with the Cottrell relationship. The plurality of current measurements are also used to calculate total charge transferred, Q. Q can then be used as a second means of calculating the final result.
